| dc.description | Framework design could play a role in the various mode of failures in fiber reinforced composite fixed dental prosthesis (FRC-FDP). The most common failures seen was the delamination of external composite of the pontic. The aim of this in-vitro research was to investigate the effect of different framework designs on the failure of FRCFDPs by determining the load and the time of initial failure; followed by a repair protocol to determine post crack performance of the framework with the highest failure load. Thirty FRC-FDPs replacing a mandibular second premolar were fabricated. Three designs were evaluated: Group A, two horizontal FRCs topped with one perpendicularly placed short FRC; Group B, modified Group A design with the short FRC placed between the two horizontal FRCs; Group C, two horizontal FRCs encircled by a parallelly placed short FRC. All samples were subjected to static loading test from the occlusal direction (v=1mm/min) using Universal Testing Machine and acoustic emission analysis was performed concurrently. Statistically analyzed data showed significant differences between the three designs (p<0.001) where Group A exhibited the highest initial failure load (568.56±113.20N). As for the time of initial failure, a statistical significance between the three groups (p<0.001) was found with Group C having the lowest value (6.60s). Six samples from Group A with failures showing composite delamination were selected for repair with same testing procedures. The initial failures of FRC-FDPs were significantly different after repair (p=0.01). This study concluded that an improved framework design substantially enhanced the performance, however, with limited potential in repairability,Ijazah Doktor Pergigian Klinikal (Pergigian Restoratif) | - |
